"Performance Evaluation of TPM-based Digital Wallets," in
Proceedings of the 2010 International Symposium on Performance Evaluation of Computer and Telecommunication Systems,
2010, pp. 179-186.
The Trusted Platform Module (TPM) manufactured
and promoted by the Trusted Computing Group (TCG) is
an embedded chip found on laptops and desktops and is fast
becoming a standard component on most computing systems.
Previous work in trusted computing-based research has suggested
that we can facilitate e-commerce transactions such as digital
wallets, e-cash and offline payments using TPMs. In this paper,
we experimentally evaluate the performance of digital wallets that
are implemented using TPM-based functionality. In particular,
we study how different approaches of implementing TPM-based
monotonic counters that are used in the digital wallet application
can perform with respect to time and cost, experimentally
evaluate and compare how each of these approaches perform
under conditions like different workloads and distributions, and
how they perform in non-standard environments where one
would need a simulator to estimate performance.
